Abstract (en)
[origin: WO2019144978A2] Disclosed herein are methods, systems, and apparatus, including computer programs encoded on computer storage media, for identifying copyrighted material based on embedded copyright information. One of the methods includes generating, by a computing device, a unique identifier (ID) based on copyright information associated with digital content, wherein the copyright information and the digital content are recorded on a blockchain of a blockchain network; identifying a plurality of color values associated with one or more color attributes of at least a portion of the digital content; and embedding the unique ID in the digital content by changing one or more color values of the plurality of color values to be representative of the unique ID, wherein the embedding produces information-embedded digital content that enables retrieval of the copyright information from the blockchain based on the unique ID, and wherein a visual difference between the digital content and the information-embedded digital content is not apparent to an unaided human eye.
